A pair of World Series of Fighting titles were on the line Friday night at WSOF 21 from Edmonton, Alberta, Canada.

Lance Palmer kept the featherweight title in the camp of Team Alpha Male, submitting Chris Horodecki in the first round with a rear-naked choke.

Palmer (9-1) has won three in a row since his first career loss in 2013 to Georgi Karakhanyan via submission. Each of his three wins since have been via rear-naked choke.

The co-main event featured former Bellator fighter Blagoy Ivanov winning the heavyweight title with a third round submission over Smealinho Rama. Ivanov missed Thursday’s weigh-ins and and hit the scale just hours before the fight.

Ivanov improved to 12-1 in his career with his sixth win via submission.

In earlier action, Hakeem Dawodu kicked off the main card with a second round TKO victory over Chuka Willis, while Thiago Goncalves, Justin Sander and Michael Hay all earned prelim submission wins.

Goncalves was facing Matt Baker as a replacement opponent. The two teammates actually shared a room Thursday night. Baker verbally submitted after the second round, citing a broken hand.
